Tread of a tire



FIG. 1 is an elevational view of a tread of a tire embodying my new design, it being understood that the tread pattern repeats uniformly throughout the circumference of the tire; and,

FIG. 2 is a perspective view of the tire tread shown in FIG. 1.

The broken line showing of the tire inner bead and sidewall is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tread of a tire, as shown and described.
